| Abstract Scope |
A simple and facile method was utilized to fabricate carbon nanotubes- nickel/nickel oxide core-shell nanoparticles (CNC) heterostructures. Nickel nanoparticles from thermal decomposition of nickel salt were nucleated on well-dispersed carbon nanotubes to form heterostructures. Various chemical synthesis parameters, post-fabrication processing, and carbon nanotube surface chemistries were studied to manipulate nanoparticle coverage density, size, shape, oxide shell thickness, and magnetic properties. Alignment of these heterostructures on a large area substrate was also achieved. Such a patterning of heterostructures is of great importance for magnetic devices, supercapacitors, and 3-D nanoarchitectures. |
